Hi Kieren,

the attached was once coded in the now down German Forum by Arnold.
Please be aware of the problems, let me quote the comment for
'unicode-diacritics':
"
; These are the UNICODE ranges of the diacritical symbols, which
; should not be insulated form their predestinating glyph.
; Look at the code charts at www.unicode.org for more information.
; As long as this table is entered manually there is a high risk of errors.
; This list (ascending order) tends to be incomplete
"


Furthermore I tested with my experimental guile-2.2.1-lilypond-build:

\markup \box #(map string (string->list "名字äüö\\letterspacing"))
\markup #(map string (string->list "名字äüö\\letterspacing"))
\markup
  \override #'(word-space . -0.2)
  \line #(map string (string->list "名字äüö\\letterspacing"))
\markup
  \override #'(word-space . 2)
  \line #(map string (string->list "名字äüö\\letterspacing"))

Returning the attached png.
Though, don't try it with guilev1-lilypond.
It will return wagonloads of pango-warnings and bad output...
